CONTAINER Filed April 17; 1959 12v VENTOR ARCH/E M M-fC'L/QEY HASATTORNEY Patented Sept. 30, 1941 UNITED STATES PATENT OFFICE commaArchie W. McClary, Oakland, Calif. Application April 17, 1939, SerialNo. 268,203 "6 Claims. (01. 220-73) My. invention relates generally tocontainers and more specifically to metal drums or barrels particularlyadapted for the'handling. of fluids such as oil or gasoline.

In the'handling storage and shipment of inflammable volatile fluids suchas oil and gasoline it is important that the container used should notonly be strong and durable in construction so as to withstand hard usagebut that it should be of light weightand so constructed that no leakageof the contents will occur at the juncture of the walls particularlywhen the walls are subjected to deformation and damage through roughhandling.

It is, therefore, an important object of my in- .vention to provide alight weight container that will stand up under rough usage with minimumdanger of leakage.

Another object f my invention is toprovide a metallic container whereinthe edges of the chime folds are-fused together to prevent leakagetherebetween. r A further object of my invention is the provision of alight weight metallic container employing a reinforcing strip to whichthe edges of the chime folds are welded. l

Still another object of my invention is the provision of a metalliccontainer wherein the edges of the chime folds are welded to areinforcing strip in such manner that the closure sheet for the ends ofthe container may be readily severed for removal and welded togetherupon replacement.

Another object of my invention is the provision of a metallic drumemploying an external strip or ring of metal highly resistant todeformation and to which the chime folds are fused.

The invention-possesses numerous additional objects and features ofadvantage, some of which, together with the foregoing, will becomeapparent upon perusal of the following description of my invention. Itis to be understood, however, that I do not limit myself to thisdisclosure of the species of my invention as I may adopt variantembodiments thereof within the scope of the claims.

Referring to the drawing:

Figure 1 is a fragmentary view in perspective of a cross-section takenthrough one comer of a container embodying my invention but with theparts separated and unwelded to clearly lar body sheet of relativelythin metal which at its. top is peripherally folded outwardly anddownwardly to provide a channel. A reinforcing ring or strip is providedto seat in said channel and is preferably of greater width than thedepth of said channel so as to project beyond the end of the fold. Acover sheet formed of similar material t that of the bodyis provided andis folded upwardly, outwardly and downwardly to provide a-recessedshoulder adapted to, closely seat over the folds of the body sheet andform an end closure for the container. The folds of the sheets are thenfused to each other and to the reinforcing ring thus permanentlyjoining:

damage to the chime I provide a capping ring which fits over the-top ofthe chime.

In greater detail, the structure of my invention as illustrated in 'thedrawing comprises a relatively thin tubular body sheet 4 of steel orother fusible metal alloy which is. folded outwardly and downwardly inthe manner shown in the drawing to provide a marginal flange 6 having acontinuous channel 1 adapted to snugly receive a ring or strip 8. Thisring I prefer to form of a fusible metal alloy possessing high tensilestrength so as to resist deformation and serve as a reinforcement forthe rim or chime of the container.

In order to close the end of the container I provide a cover sheet 9formed 01' material simia marginal shoulder H having a continuous recessl2 therein complementary to and within which the flange 6 of the bodysheet is adapted to fit. The juxtaposed edges of the shoulder. flangeand rim are integrally fused together as indicated by the numeral IS inFigures 2 and 3, either by resistance or metallic arc welding thuspermanently sealing the space between the folds of the fiange andshoulder to prevent leakage therebetween and providing a rim or chimeof.

great strength and durability. The folds which form the chime or rim ofthe container further provide with the ring a. reinforced bearingsurface upon which the drum may rest or be suppo ted during transortation or storage. Such terminate above the outer edge of the flangein order to facilitate fusing of the parts by means of resistancewelding. 1

While the structure thus far described is highly satisfactory, I havefound it advantageous to protect the chime by providing a removablecapping ring ll therefor which is designed to further strengthen thesame as well as to prevent direct damage thereto in the event thecontainer is subaas'mer disposed within an open end of said body formedof a sheet of said similar material and folded outwardly to overlap andsubstantially enclose the fold of said body, and said body and closurefolds being integrally fused together and to said strip along a regionlongitudinally spaced from the marginal edge of said tubular body.

3. Acontainer comprising an open-ended tubular body formed of a sheet offusible material folded outwardly and downwardly along a marginal edgeto provide a continuous chann'elwhich jected to a blow or is dropped ona sharp edged or cornered object. I p

In practice the interior surface of the container is ordinarily providedwith a galvanized,- enameled or other well known type of protectivecoating. Injury to such coating is to beavoided and by my invention thisis accomplished for it will be observed that the fusion of the folds andrim takes place a substantial distance from the interior surface of thecontainer which is, thereand having an annular recess formed on theinfore, not affected by the heat generated during the welding operation.

I wish to point out a further'advantageous fea+ ture of my'invention. Inthis connection it will be observed that the folds of the chime arefused is substantially rectangular in cross-sectional contour, a stripof similar material snugly disp'osed in'said contour, a closure disposedwithin 15 an open end of said body'and formed of. a sheet of saidsimilar material and having 'itsedge folded to overlap the fold of saidbody'with the edge thereof terminating adjacentthe edge of said bodyfold, and said 'foldsbeing integrally fused together and to said stripalong a region longi 1 tudinally spaced from the marginal edge of saidtubular body. Q 4. A container ner face thereof,-a closure disposedwithin an open end of said body-formed-of a sheet ofsaidsimilarmate'rial and folded to overlie the fold of saidbody,andsaidbody and closure sheets beonly along their lower edges;therefore, if the outer fold of the chime is sawed or otherwise out athrough above the point of fusion, the cover sheet may be lifted ofl thecontainer body to permit of resurfacing or cleaning of the interiorthereof and thereafter such sheet may be replaced and the severed edgesof the fold readily welded together. It is, therefore, obvious that myinvention lends itself to the simple and economical repair of thedamaged interior ofcontainers and has thereby solved a costly anddiiflcult problem in the trade.

In Figure 3 I have shown a modified form of my invention. Here. thereinforcing ring 8 is provided with a continuous depression I! in oneside thereof while the adjacent folds of the body and cover sheets arecorrespondingly deformed as at Hi to rest therein; thus added strengthis given to the chime and the folds are restrained from separating.

I claim: a

A container comprising an open-ended body sheet, a backing ring ofsubstantially rectangular cross-section, surrounding said body sheet anda cover sheet engaging said body sheet at an open end thereof, each ofsaid sheets having an edge thereof in relative juxtaposition and foldedoutwardly over said backing ring, and substantially enclosing the sameon three sides, said sheets being homogeneously joined together and withsaid ring along said juxtaposed edges.

2.

I tial portion ofsaid edge walls freely separable similar peripheral channel-shapedflange terminating in an edge wall substantially concentric with thebody sheet, and a closure sheet positioned across the open end of saidbodysheet and terminating in an edge wall adjacent said first mentionededge wall, a ring encircling said body sheet within said body sheetperipheral channel, said adjacent edge walls being integrally united toeach other along their edges and to said ring, leaving a substanuponcutting through said closure edge wall along a line adjacent the weldededge portion.
